Here Are Apple's Full Release Notes for iOS 18.3

Apple provided developers and public beta testers with the release candidate version of iOS 18.3 today, and with it comes release notes confirming what's new. While we knew about several of the features that are in the update, there are some lesser known tweaks and bug fixes.

iOS 18
The update adds new Visual Intelligence features for iPhone 16 models, it tweaks Notification summaries on all devices that support Apple Intelligence, and there are also bug fixes for Siri and Apple Music.

Visual intelligence with Camera Control (All iPhone 16 models)
- Add an event to Calendar from a poster or flyer
- Easily identify plants and animals

Notification summaries (All iPhone 16 models, iPhone 15 Pro, iPhone 15 Pro Max)
- Easily manage settings for notification summaries from the Lock Screen
- Updated style for summarized notifications better distinguishes them from other notifications by using italicized text as well as the glyph
- Notification summaries for News & Entertainment apps are temporarily unavailable, and users who opt-in will see them again when the feature becomes available

This update includes the following enhancements and bug fixes: - Calculator repeats the last mathematical operation when you tap the equals sign again
- Fixes an issue where the keyboard might disappear when initiating a typed Siri request
- Resolves an issue where audio playback continues until the song ends even after closing Apple Music

Some features may not be available for all regions or on all Apple devices. For information on the security content of Apple software updates, please visit:

The release candidate version of iOS 18.3 represents the final version of the software that will be released to the public in the near future should no additional bugs be found;

We are expecting iOS 18.3 to see a launch alongside iPadOS 18.3, macOS Sequoia 15.3, tvOS 18.3, visionOS 2.3, and watchOS 11.3 next week.

The Apple Intelligence rollout (and hilariously, rollback) is truly a software blunder for the ages. $3.5T company can't ship the features nobody wanted anyways. Scott Forstall was fired for less! I would enjoy reading an insider story on the whole development of AI at Apple. You can just feel how at-odds the whole thing is with the company's and products' strengths.

Today I tried to get Siri to give me the average of several numbers today. No matter what I tried, saying "find the average of 19, 17 and 15" for example, was always parsed by Siri as the average of 1917 and 15.

Also, "set timer for four minutes" almost always results in a 44 minute timer.

There's no point to a voice assistant that takes more effort to get it to respond correctly than just doing something manually.

Siri is complete trash.

You may be surprised. AI itself is in its infancy.

The 'Improved Siri' is the litmus test for me. Everything else is environmentally ruinous and dubiously data-sourced treats for early adopters. Missed the days when the idea of a digital assistant calling back a doctor's office to reschedule an appointment seemed just around the corner. That kind of feature could really help people.

I hope it breaks TikTok and people have no way to update the app.
